4 Power Train The 854G power train delivers top performance and durability in tough applications Cat 3508B Diesel Engine. Is a fourstroke design and uses long, effective power strokes for more complete fuel combustion and optimum efficiency. (1) It is designed with large displacement and a low speed rating for long hours of service between scheduled overhauls and lower operating costs. Torque Rise. Of 30 percent provides high lugging force during dozing and acceleration in high rimpull conditions. The torque curve effectively matches the transmission shift points to provide maximum efficiency and faster cycle times. Electronic Unit Injection (EUI). Is a proven high-pressure, direct injection fuel system that electronically monitors operator demands and sensor inputs to optimize engine performance. ADEM II (Advanced Diesel Engine Management System). Controls the fuel injector solenoids to start and stop fuel injection. This system provides automatic altitude compensation, air filter restriction indication and will not allow the engine to fire until it has oil pressure, acting as cold start protection and a form of pre-lube. Separated Cooling System. Isolates the radiator and fan from the engine compartment providing lower sound levels, more efficient cooling and a sloped hood for increased viewing. (2) Advanced Modular Cooling System (AMOCS). Improves cooling capabilities by using a parallel flow system with 16 cores. Serviceability is improved with AMOCS as there is no top tank to remove and the radiator guard does not have to be tilted to remove the cores. 4

5 Separate Circuit Aftercooling (SCAC). Dedicates six of the radiator s cores to the independent aftercooler circuit. This allows the aftercooler circuit to operate cooler, resulting in denser air charge and improved emissions. Additional Engine Features. Include: Two-piece piston with steel crown (three rings) and thermally isolated aluminum skirt Copper-bonded crankshaft bearings Hardened crankshaft journals Two hard faced inlet and exhaust valves per cylinder, valve rotators and hard alloy-steel seats Self-aligning roller followers on camshaft Dry-type radial seal air cleaners with primary and secondary elements and precleaner Direct electric 24-volt starting system with 100-amp alternator and four 190-amp-hour, low-maintenance, high-output, 12-volt batteries Caterpillar Planetary Power Shift Transmission. Features perimetermounted, large diameter clutch packs that control inertia for smooth shifting and increased component life. (3) The electronically controlled transmission enhances productivity, durability and serviceability. Top side power train filter removal Final Drives. Feature planetary reduction at each wheel. Torque is developed at the wheel, which gives less stress at the axle shafts. The planetary units can be removed independently from the brakes. 20% Rimpull Selected Brakes (20% Rimpull) 100% Rimpull Selected Left Pedal Impeller Clutch Torque Converter (ICTC). Combined with the Rimpull Control System (RCS) allows the operator maximum flexibility in modulating rimpull. (4) Improved calibration procedure Improved left pedal modulation Compensates for wear by providing the ability to recalibrate for optimum left pedal modulation regardless of torque converter wear. The impeller clutch torque converter uses the left brake pedal to modulate rimpull from 100 to 20 percent of available rimpull for reduced tire slippage. After 20 percent is achieved, further pedal travel applies the brake. The RCS selector dial is used to select the desired rimpull setting from four factory presets (Maximum, High, Medium and Low). The reduced rimpull is only active in first gear forward. RCS will allow the operator to match rimpull to ground conditions. The torque converter is equipped with a lockup clutch for direct drive efficiency in second and third gear. ICTC is standard with lock-up and free wheel stator. Heavy-Duty Axles. Feature standard axle oil coolers, permanently lubed universal joints and stronger axle components in both the differentials and final drives for increased performance, serviceability and durability. (5) Free floating axle shafts can be removed independent of the wheels and planetaries for quick and easy servicing. Axle oil cooling system circulates oil from the brakes and differentials through an oil-to-air cooler that provides increased oil life while extending component performance and durability. Conventional differential is standard. Oil Enclosed, Multiple Disc Brakes. Are adjustment-free with fewer parts for improved serviceability. (6) Fully hydraulic actuators with independent front and rear circuits use separate accumulators and new valves for increased performance and reliability. Brake location improves serviceability. The axle shaft brake design allows brake service while leaving the final drive intact. Axle shaft brakes require less force by operating on the low torque side of the axle. Combined with improved axle oil circulation for increased cooling, the oil enclosed, multiple disc brake design improves durability. Service Brakes. Are four wheel, hydraulic, oil-dipped multiple-disc brakes that are completely enclosed and allow modulated engagement without slack adjusters. Parking Brakes. Are spring applied, oil-released, dry disc that are mounted on the transmission transfer gear output shaft. Manual override is possible to allow movement of the machine. Secondary Brakes. Will trigger the electronic monitoring system to alert the operator if pressure drops and then automatically applies the parking brake. 5

6 Structures Superior design and strength provide solid support for maximum production and service life Castings. In the engine end frame are used in critical high-stress areas to help spread the load and reduce the number of parts. The casting for the rear trunnion mount also serves as an engine mount, which provides a load path for the weight and torque of the engine to travel down to the trunnion and then on through to the axle. Other castings used in the engineend frame include: front trunnion mounts, steering cylinder brackets, articulation stops and lock link. Full Box-Section Frame Design. Has been redesigned for increased strength. Internal and external members have been added to the rails in critical sections. (1) The heavy-duty, boxsection front frame provides maximum structural strength to resist twisting loads experienced during dozing. (2) Upper and Lower Hitch Pins. Pivot on a double-tapered roller bearing. (3) The upper hitch plate thickness has been increased and the lower hitch plate has been extended to improve transition to the rail assembly. Spread Hitch Design. Helps square up the frame and provides more clearance for hydraulic lines. (4) Double tapered roller bearings and hardened pins resist both horizontal and vertical loads to increase life. The spread-hitch also makes service access easier. Engine and Transmission Mounts. Are designed to use mushroom and cup-shaped ISO mounts, reducing component vibration and sound levels. The engine mounts directly to the rear cross member, simplifying and improving load transfer structure. 6

7 Hydraulics Well-balanced hydraulics deliver precise, low-effort control and trouble-free operation Separate Hydraulic Systems. Feature one system for the brakes and steering and another for blade control and the hydraulically-driven engine cooling fan with full flow filtering. (1) The benefits of the separate hydraulic systems are increased cooling and elimination of cross-contamination. XT-3 and XT-5 hose and reliable components help reduce the risk of leaks and blown lines, helping protect the environment. Reusable O-ring face seals make servicing easy. Tandem gear pumps provide hydraulic flow for the lift, tilt and tip functions. Well-proven pumps, valves and cylinders are common with those used on large Caterpillar Track Type Tractors. For improved serviceability, all hydraulic pumps are mounted on a single pump drive. Case Drain Filtration. Is included throughout the hydraulic system to protect against contamination. (3) Easily accessed for serviceability, seven filters protect the hydraulic pumps, fan motor and axle oil cooler circuit. Optional high pressure screens are available as an upgrade to the case drain filtration package. This deluxe filtration package places high pressure screens on the output side of the hydraulic pumps, further protecting the hydraulic system from contamination. Load Sensing Steering. With STIC Control System is a revolutionary system that integrates steering and transmission into a single controller. (4) The variable displacement pump maximizes machine performance by directing power through the steering system only when needed. Simple side-to-side motions of the operator s left arm turn the machine right or left. Transmission shifting forward, neutral or reverse is controlled by the operator s fingers and gear selection is controlled by the operator s thumb. Blade Control. Floor-mounted controls adjust lift/lower and tilt/tip blade functions. (2) 7
